dm: handle failures in dm_table_set_restrictions
If dm_table_set_restrictions() fails while swapping tables,
device-mapper will continue using the previous table. It must be sure to
leave the mapped_device in it's previous state on failure. Otherwise
device-mapper could end up using the old table with settings from the
unused table.
Do not update the mapped device in dm_set_zones_restrictions(). Wait
till after dm_table_set_restrictions() is sure to succeed to update the
md zoned settings. Do the same with the dax settings, and if
dm_revalidate_zones() fails, restore the original queue limits.
Fixes: 7f91ccd8a608d ("dm: Call dm_revalidate_zones() after setting the queue limits")
